Clash Verge Rev vs FlClash vs Clash Plus: Client Comparison

Quick overview of the three clients

Positioning matters before comparing details. Clash Verge Rev is the community fork that carries on after the original Clash Verge stopped maintenance, built on Tauri and focused on Windows and macOS desktop. Its UI leans toward an engineer-friendly style, exposing configuration options quite thoroughly. FlClash is a cross-platform client written in Flutter, covering Windows, macOS, Linux, and Android, known for a polished and easy-to-use Android build — a good fit if you want a consistent experience across phone and desktop. Clash Plus takes a different route: as an iOS client available directly on the App Store, it fills the gap neither of the other two can reach — system-level proxying on iOS — with interaction design closer to native iOS conventions.

All three share largely compatible rule engines and subscription protocols based on the same YAML config syntax, meaning the same subscription link can, in theory, move between clients. The real differences show up in resource scheduling, UI presentation, and platform-specific capabilities.

Resource usage and background behavior

"Resource usage" means different things on desktop versus mobile — desktop is about memory and CPU footprint, while mobile is about battery drain and background-survival strategy.

Because Clash Verge Rev's UI layer is a native WebView container over a Rust backend, its desktop memory curve stays fairly restrained, and it's unlikely to creep up gradually during long runs. FlClash's Flutter render layer adds some overhead, but in exchange gets a highly consistent UI across Windows, macOS, Linux, and Android, which keeps maintenance costs down and update cadence steady. As an iOS app, Clash Plus's memory footprint is bounded by the NetworkExtension sandbox, so battery consumption is the more relevant thing to watch — check that the proxy mode and survival behavior in Settings match your expectations.

TUN mode support and differences

TUN mode means the client sets up a virtual network interface at the system network layer to capture all traffic. Compared with traditional system proxy settings, TUN mode covers more apps and protocols that don't respect system proxy settings (such as some UDP traffic and non-HTTP connections).

• Clash Verge Rev: Full TUN mode support on desktop. Windows needs the accompanying TUN driver component installed; macOS requires granting a system extension permission. Once enabled, it captures nearly all outbound traffic, suiting users who want fine-grained control over low-level network behavior.
• FlClash: Also supports TUN on desktop; on Android it achieves a similar effect via the system VPNService interface, with the setting inside the app's network settings — the first activation triggers a VPN permission prompt.
• Clash Plus: iOS itself has no TUN interface mechanism. Instead, it captures traffic system-wide through a proxy profile defined via the NetworkExtension framework, which is functionally equivalent to desktop TUN mode but implemented on a completely different path — a limitation of the iOS platform, not a missing feature.

Subscription management and rule updates

Subscription management determines how easy day-to-day maintenance is, and each client takes a slightly different approach.

Clash Verge Rev supports multiple concurrent subscriptions, subscription grouping, manual update intervals, and per-subscription User-Agent and refresh settings — a good fit for managing several provider subscriptions at once. FlClash's subscription UI leans toward a card-based layout, with short paths for adding a subscription, switching between them, and checking usage — low learning cost across platforms. Clash Plus simplifies subscription import, supporting links, QR code scanning, or sharing from other apps, with a fairly complete first-run walkthrough that lowers the barrier for iOS users setting up a proxy for the first time.

All three behave the same way in one respect: updating a subscription re-fetches the node list and rule set from the remote config, but local group ordering and custom rules are typically preserved and not overwritten — worth confirming before switching providers or refreshing a subscription, so you don't mistake this behavior for lost local configuration.

UI complexity and learning curve

Interface complexity tends to scale with "how professional" a client feels, so weigh this against your actual needs.

1. Clash Verge Rev

   Exposes more configuration in the UI — rule editing, script enhancements, and proxy-group weight adjustments are all accessible directly, suiting users willing to learn Clash's config syntax; there's a real learning curve for beginners.

2. FlClash

   Leans on more sensible defaults and guided design — common actions (switching nodes, switching modes, checking latency) sit on the home screen, while advanced features like rule editing live in a secondary menu, balancing ease of use with feature completeness.

3. Clash Plus

   Follows native iOS interaction conventions, with settings grouped in a style matching the system Settings app. Subscription import, VPN authorization, and mode switching all follow iOS users' existing habits, requiring almost no learning curve.

Platform-specific recommendations

To keep configuration consistent across multiple devices on the same account, use one subscription link and install the appropriate client on each platform, rather than forcing the same client everywhere — the rule syntax is interchangeable across all three, so switching clients won't break your subscription.
